CRYOGENIC STRETCH-FORMING OF SOLID-PROPELLANT ROCKET CASES,
Abstract
Ten subscale preform vessels were fabricated and cryogenically stretched. Four of these were trial units, stretched at various stress levels. The final six units were all stretched at the same stress level to determine reproducibility of shape and conformance to blueprint dimensions. Room-temperature hydrotests were conducted on the four trial subscale vessels. In addition, a vessel which had been stored for one year after cryogenic stretching was hydrotested. The results indicate that properties do not deteriorate with time. Profile measurements were taken on the six stretched subscale vessels. Small deviations from blueprint dimensions were observed in both the forward and aft closures. (Author)
